Watch strap help to restore my/dad's watch to original
When I was a child in the early 2000s, my first big boy watch was a Timex Expedition. I was a very outdoorsy kid and I remember being really proud of it and wearing it until the strap fell to bits.
I guess I "outgrew" it and left it at home and it turns out my dad adopted it and wore it for quite a number of years until he died a few year ago. My mum gave me the watch and I wore it until the generic strap she'd put it on also broke.
I'd really like to return it to original if possible but I can't pin the specific watch model down and there is no model number on the case. However, pic 2 is what I am certain is the strap that was on it originally, and it's from a single listing I've found, where it's no longer available: https://www.watchbattery.co.uk/shop/products/WSTX-9T77862.shtml
The canvas section was blue/brown, I've found some that are green/brown (also out of stock) but it was certainly blue, like this listing/picture. And it is 18mm at the bar.
I'm not very good at the ol' AI but I "asked" it to search based on the picture, and it suggested that some places occasionally do sell dead stock of old/obscure watch straps and I wondered if anyone had any tips about tracking this down.
